To eil 207mm t may concern:

Be it' known that I, JOHN KnLsnY, a citi'- zen of the United States, and resident of `Detroit, in the county of Wayne 4and State ol Michigan,l have invented certain new as" `i useful Improvements in Interchangeable S -lit Tire-Holding Rims, of which I hereb'L declare the following to be a full, clear, an exact-description, such as will enable oth. s skilled in the'art to which it apper-4 taine make and use the same. l p

The objects of the invention are to provide an improved and simplied construction of split tire holding rim in which one form is adapted for use interchangeably with a clencher or straight sided tirefand in which the form to be lused with clencher tires will meet all requirements of the tire association `for standard clencher tires.

Y ployed to secure sided tire having lor oversize, and therefore This improved form of rim permits of the use oi' standard forms of endless eide tire holding rings, which can'be used to secure clencher tires upon the rim or in reversed position will secure straight sided tires thereon. i p

A further feature of the invention lies in the reversibility of the rim in relation to the felly band, thus giving ita universal use.

In this invention the rim employed as a base for the tireand tire holding rings is.

extended laterally tol permit reversing the rings without 4hereby reducing the available base dimensions of a straight sided tire, whereby the same rings can. be emthe well known clencher tire of standard size, and also a new straight a 10% increase in volume requiring a greater width of base to effect this'result, without appearing to the eye to be oi"v larger size.

rIhis result is obtained by means of inwardly turned edges tothe which is made correspondingly wider andthus provides securing `means ofl substantially two dimensions and can be used interchangeably with either tire.

rlhe invention furtherincludes integral l securing means for the rim extremities, and engaging means for the rim and felly band.

The invention further consists inthe combination and arrangement oi" parts and construction of the various detailsv shown in theaccompanying drawings and specifically pointed out in the claim. j

-drawal from the 'felly sides B2, B2

, In the accompanying drawings Figure l 1s a transverse section of a clencher tire mounted upon the improved form of rim, and showing the reversible method of engagingthe rim with the telly band; Fig. la is a transverse-section of the double wedge clamping ring; Fig. 2 is a similar view showing the manner of adapting the same rim to a straight sided tire having a wide base; Fig. 3' is a side elevation of the assembled rim and felly band showing one of the clamps for securing the rim upon the felly band; Fig. 4 is a longitudinal section of the felly, felly band, and rim, showing a projection upon the rim which is adapted to enter interchangeably one of two openings in the felly band according to the position to prevent creeping of the rim on the band, this construction permitting Vreversing the position of the rim upon the band; Fig. 5 is a side. elevation showing the extremities 'of the split rim separated after withband to permit the removal ofthe tire, and showing the integral means for securing the ends together when the parts are assembled; Fig. 6 is a transverse section of the rim on line Fig. 5; Fig. 7 is a plan view of the felly band showing openings for the valve and for the vprojections upon the inner surfaceof the tire holding rim; Fig. 8 is a transverse section of the felly and felly band.

In these views IA is the rim which is adapted to .retain upon its margins the tire holding rings B,

In Fig. l these rings are shown in the position .for holding a clencher tire, their curved outer edges B extending inwardly to overlap the clencher edges C', C of a tire C.

These rings are retained in position by means of inwardly curved outer edges A', A of the rim A. These edges form annular Hanges extending around the cuter edges of the rim A and when the straight sides B2, B2 of the tire holding rings are turned outwardly, their outer sides will engage the extreme inwardly turned edges A, A of the rim A, and the curved vedges B', will overlap the clencher edges of a tire of standard dimensions as shown in Fig. l. When the tire holding rings are reversed in position, as shown in Fig. 2, their straight 'zol are arranged to securea straight p a straight sided tire of much broader base4 than would be possible with the use of straight and will enable the user to increase the capacityof the straight sidedtire with the use of the same rim upon which he can' mount'a clencher tire if desired. This construction increases the value of the rixn and gives it an interchangeable and double use.

This 'form of rim is split upon a plane inclined to the axis of the wheel as shown y in Figs. 3 and 5 to make it possible to collapse the same when the tire is placed upon v itv or withdrawn therefrom.

vTo lock the parts inplace when assembled, integral detents or wedge shaped tongues a, a, are cut from the body of the rim in one extremity closely adjacent to the inclined end, and when the opposed inclines are drawn into contact with each other the wedge shaped tongues upon one extremity will spring underneath the other extremityv and secure the extremities in alinement with each other.

To disengage the extremities after the yrim is removed from the wheel,l a groove G is cut in the edge of one of the ianges A', A and a tool is insertedunderneath one of the rings B and by prying 'one end of the rim downward the locking tongues can easily be disengaged and the rim. will collapse suiiciently to permit the removal of the tire.

The tongues a, a, are preferably drawn to a relatively sharp edge -to make their action prompt and eicient in securing the ends together.

The rim A is assembled upon a felly band H which is secured to the felly H of the wheel. The engaging surfaces of the rim and felly band are so constructed that the rim can be sleeved over the band from either side, thus making it' substantially'universal in use.

To accomplish this result the rim is provided with duplicate annular integral ribs R, R, on its inner circumference. The outer faces of these ribs are reversely inclined and are inclined toward the center of the wheel and are equally spaced from the center of the rim. c

The felly band is provided with a corresponding annular marginal incline R in' its inner edge, inclined toward the center of the wheel, against whichone of the inclines upon the rim is seated when the rim' is put in place.

The outer edge of lthe felly rim is pre@- vided with an inwardly turned ange R2 marginal flanges upon the rim A,

Lacasse? sponding inclined surfaces W2, W2, engages with the opposed 'inclines upon the rim and felly band.

The inclines are preferably duplicated upon two sides of the wedge ring so that it will be reversible and no mistake can be 'made in placing the same.

The rim and felly hand are clamped together by means of clamps K which are suitably spaced apart around the felly band and are retained in position by means of bolts L, L, which pass through the felly H. Nuts M are adjustable upon the outer ends of the bolts and are preferably provided with anges m which are inclosed within the recesses m in the' clamps K.

The margins of the recesses are turned inwardly at mzto retain the nuts and prevent them from escaping from the clamps, an an nular sheet metal cup shaped washer m3 in each recess prevents excessive friction as the nut is turned and a split ring shaped spring fm;i retains the clamp temporarily at any angle at which it is placed.

Each clamp is provided with a heel m5 which rests upon the downwardly turned flange R2 and the clamp rocks upon this heel when pressed against the doubie wedge. To facilitate -the rocking action and so as not to cramp the nut, the heel should not be placed farther from the bolt than the margin of the nut, and the inner nut and the recess in the clamp are preferably crowned or correspondingly curved so as to form a near approach to a ball bearing for the nut.

Lugs M, M6 upon the nuts and pins inserted at h, h, in the flange of the felly rim prevent the clamps from being turned too far when separating the parts and insure their being all turned alike, thus facilitating the assembling of the parts.

surfaces of To prevent the rim from moving circumferentially upon the felly band the band is provided with a radial opening S in each side of the usual opening T for the valve T as shown in Fig. 4, and a pin t is secured in the rim which is inserted in one of these openings when the parts are assembled..

The two openings are equally distant from the center of the valve opening so that the pin will enter one of these openings whichever side of the rim is first presented to the felly band.

The rim is in this manner universal in its mode of application to the felly band and also can be interchangeably. used with a could be usedwth an ordinary rim Having deserbed lthe invention what iap ing extremities having corresponding filaire asnew and desire to secure by Letters me ined meeting surfaces arranged to fa- 10 4eteut is: eilitate .separating and reuniting the exn e, spllt rim, u. body portion provided tremities.
